Sayyiduna Malik bin Buhaina (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) saw a man who, after the takbir, was performing two rak‘ahs of prayer. When the Prophet (peace and blessings be upon him) finished the prayer, people gathered around that man, and the Prophet (peace and blessings be upon him) said: "Are you performing four rak‘ahs of the morning prayer? Has the morning prayer become four rak‘ahs?"
